When I worked mainteince on a big chain hotel in a major college town, we had a mark 2.0 crowbar if the key card didn't work. The real fun one was the flippy locks that you could kinda pop by slapping the non-working key card in, and slamming the door. The card would flex and spring the lock back. Then you could use the crowbar again. It wasn't too slow, but it was very loud.

They told me couldn't whistle and spin the crowbar nonchalantly before casually popping open doors that had a dead battery in front of the guest waiting to stay in that same hotel.
